Apterolarnaca

Apterolarnaca^[1] is a genus of Orthopterans, sometimes known as 'leaf-folding crickets' in the subfamily Gryllacridinae, tribe Ametrini and genus group Apotrechae Cadena-Castañeda, 2019. Records of occurrence are from southern China and Vietnam.^[2]

The prefix "Aptero-" means that these Orthopterans are similar to the genus Larnaca, but have secondarily evolved without wings (becoming apterous). There are a number of similar genera, described from Vietnam by AV Gorochov, and the Orthoptera Species File indicates that other locality records^[2] and possibly other species have yet to be discovered in the Indo-China region.
